Previously we maintained an `isInteractable` flag, which was derived from these layer flags:
- Locked/unlocked
- Enabled/disabled
- Layer's type visible/hidden
When a layer was not interactable, we blocked all layer actions.
After comparing to the behaviour in Affinity and considering user feedback, I've loosened these restrictions while maintaining safety. First, some definitions.
There two kinds of layer actions - mutating actions and non-mutating actions.
- Mutating actions are drawing on the layer, cropping it, filtering it, converting it, etc. Anything that changes the layer.
- Non-mutating actions are copying the layer, saving the layer to gallery, etc. Anything that _uses_ the layer.
Then, there are two broad canvas states - busy and not busy. "Busy" means the canvas is actively filtering, staging, compositing layers together, etc - something that is "single-threaded" by nature.
And here are the revised restrictions:
- When canvas is busy, you cannot initiate any layer actions.
- When the canvas is not busy, and the layer is locked, you initiate any mutating actions.
- When the canvas is not busy and the layer is not locked, you can initiate any layer action.
Besides safely giving users more freedom, it also fixes an issue where the context menu for a layer was disabled if it was not the selected layer.
- Add method to force a rebuild of the pydantic type adapter for the union of invocations, which is used to validate graphs.
- Update the xfail'd test.
Had missed several of these, which means we were invalidating caches far too often. For example, when you changed a RG prompt, we were invalidating the cached canvas for that entity, even though changing the prompt doesn't affect the canvas at all.
Previously, merge visible deleted all other visible layers. This is not how affinity works, I should have confirmed before making it work like this in the first place.Ï
`CanvasCompositorModule` had a fairly inflexible API, only supporting compositing all raster layers or inpaint masks.
The API has been generalized work with a list of canvas entities. This enables `Merge Down` and `Merge Selected` functionality (though `Merge Selected` is not part of this set of changes).
Let the parent module adopt the filtered/segemented image instead of destroying it and making the parent re-create it, which results in a brief flash of the parent layer's original objects before the new image is rendered.
We were scaling the unscaled image and mask down before doing the paste-back, but this adds an extraneous step & image output.
We can do the paste-back first, then scale to output size after. So instead of 2 resizes before the paste-back, we have 1 resize after.
The end result is the same.
